Answer:
x = 15
Step-by-step explanation:
Because PQ is parallel to JL, 
Substituting, we have 
5(x-6) = 3x
5x - 30 = 3x
2x = 30
x = 15
A. All the equations are in slope intercept form, so all that's needed to do is plug in 2/3 as the x value in each equation and if the result is 4, then you got the answer.
The domain and range of the given function are equal to (0, 3.85) and (0, 18.75) respectively.
<h3>How to calculate the domain of the function?</h3>
In this exercise, you're given the following function h(t) = -4.87t² + 18.75t. Next, we would equate the function to zero (0) to determine its domain as follows:
0= -4.87t² + 18.75t.
4.87t(-t + 3.85) = 0
t = 0 or t = 3.85.
Therefore, the domain is 0 ≤ t ≤ 3.85 or (0, 3.85).
<h3>How to calculate the range of the function?</h3>
h(t) = -4.87t² + 18.75t
h(t) = -4.87(t² - 3.85t + 3.85 - 3.85)
h(t) = -4.87(t - 1.925)² + 18.05
Therefore, the range is 0 ≤ h ≤ 18.05 or (0, 18.75).

Whenever there are two - signs, this means it turns into a plus. So it would be -
1+2
And it would equal 3!
A histogram is used to show the frequency of data, where the length of the bar represents the frequency.
<em>From the histogram, 50 students drank the recommended amount of water.
</em>
Given that
or more
The number of students who drank the recommended amount are students whose frequency is at least 48
From the attached histogram, only 1 bar has a frequency that is at least 48 or more
And the number of students in this bar is: 50
Hence, 50 students drank the recommended amount of water,
